APPARATUS FOR DEODORIZING THE EXHAUST-GASES OF MOTORS.

Specification of Letters Patent.

Patented Dec. 17, 1907.

Application filed April 24:. 1906. Serial No. 313.463.

T 0 all whom it may conce m:

Be it known that I, ALFRED REICIIEL, a citizen of the L'nited States,temporarily residing at Dresden-lioschwitz, Germany, have inventedcertain new and usefulimprove ments in .-'\pparatus for Deodorizing theExhaust-Gases of Motors, of which the following is a specification.

My invention relates to an apparatus for deodorizing the exhaust gasesof motors, more particularly the gases'escaping from automobiles and thelike.

The invention is illustrated in the accompanying drawing, Figure 1 ofwhich represents a vertical section of the apparatus applied to a motorcar. Fig. 2 is a vertical section taken at right angles to Fig. 1, of amodification of the apparatus, with bifurcated exhaust gas pipe. Fig. 3is a vertical sectional view of. a second modification, in which the gasoutlet pipe is provided witha valve. Fig. 4 is a vertical sectionthrough a third modification, the tankof which is furnished with aperforated partition.

Referring more particularly to Fig. 1, a is the exhaust-gas pipe fromthe motor. This pipe, instead of conducting direct to the atmosphere asgenerally, is led into a tank I). The latter may be of any suitableshape and material, such as a rectangular iron tank with a removablecover c bolted to it. The tank should be about half filled with a liquid(I, the upper half (1 remaining empty. Thel mouth f of pipe (1 lies nearthe bottom of l the tank I). At the opposite side of the tank t a pipe gconducts from the space e. The! pipe g has a bend .at g, perforated atIt. Should any of the liquid d enter the pipe 9 owing to shaking of thetank, it will thus col- 1 lect at g and escape at h into the tank again.The exit of the pipe {1 may be protected by a single or double sieve i,to prevent the entrance of dust or other foreign particles such as may,for instance, be blown toward the pipe {1 by the wind.

In the modification shown in Fig. 2, the pipe a is bifurcated so as topresent two mouths f. if desired, a pipe having three or four or moremouths might naturally be employed.

In Fig. 3 a pipe 9 is shown provided with a back-pressure valve k. Thisvalve may be employed either without or in conjunction with a sieve.

The tank I) of the apparatus illustrated in Fi 4 is provided with aperforated partition Z, for the purpose of preventing the liquid (1 frombeing thrown about to an undue extent.

In use, the exhaust gases will enter the liquid (1 through the pipe a,f, and will rise through it and enter the space 6 in deodorized conditioHere they will collect and the odorless g s will flow out through pipeg.

The advantage of the bifurcated pipe a, shown in Fig. 2, is that the gasis better distributed, since it does not all have to pass through thesame single passage.

1 do not desire to restrict myself to any particular liquid, sincevarious kinds may be employed. I have found any oil which is not toothick, and which emits an agreeable, aromatic odor, to be particularlysuitable.

I Any other oil however may be employed; or

instead of an oil, any other appropriate liquid, among which water, itwould appear, may be classed, particularly if some deodorant is added toit. The liquid may be run off at intervals and a fresh supply let intothe tank. Or the spent liquid maybe filtered and re-used in the tank.

Having thus described my invention, 1 claim as new and desire to secureby Letters Patent:-

Apparatus for deodorizing the exhaust gases of motors, comprising a tankpartially filled with a suitable liquid, means for conducting theexhaust gases from the motor into the said tank close to the bottomthereof, outlet means for the deodorized gases communicating with thetank above the liquid level, comprising a double knee piece havingperforations at the lowervbend and means for preventing entrance offoreign matter into the outer end of said knee piece, and means forpreventing the liquid from being violently thrown about within saidtank, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
